Problems solved by technology

However, in order to efficiently use short access slots, the amount of data to be transmitted must be reduced
[0007] Therefore, the transmission of large redundant data volumes caused by lost cooperation becomes more and more problematic and inevitably leads to process interruptions
Furthermore, because the current mobile production process can be operated smoothly only if all mobile units are connected, so-called secondary monitoring impairments can occur

Embodiment approach 1

[0059] Embodiment 1: Method for transferring data from peers to backend systems

[0060] Below, based on figure 2 and image 3 A method according to the first embodiment will be described. According to the invention, if there is no connection to the backend system, data is exchanged between mobile units (peers) over a mobile ad hoc network, eg WLAN or in unlicensed Industrial Scientific Medical (ISM) frequency bands.

[0061] If a connection is available between the backend system and the mobile unit, the master index (MIB) of the master database (MDB) of the backend system is transmitted to the peer. Based on the MIB, the peer determines which of the collected data has to be sent to the MDB of the backend system.

[0062] In the backend system, the data exchange management service (DEXMB) of the backend system generates MIBs from the data received by the peers in the MDB, and then transmits them to the peers. At the same time identify the final transmission of the new ...

Embodiment approach 2

[0083] Embodiment 2: Method for transferring messages from backend systems to peers

[0084] Below, based on Figure 6 and Figure 7 A method according to the second embodiment will be described. According to the invention, if there is no connection to the backend system, messages are transmitted from the backend system to the peers via other peers. Between mobile units (peers), the transmission takes place via a mobile ad hoc network such as WLAN or the unlicensed ISM band.

[0085] In the peer, DEXMP generates the recipient message (ENIP) of the peer from the received messages of the backend system to the peer.

[0086] In the local DEXMP of a peer, a local message index (LNIP) for other peers is additionally generated from the locally stored messages of the backend system.

[0087] If the connection between the backend and the mobile unit is available, the backend transmits to the peer its master index (MIP) of the message that the peer has acknowledged The LNIP is t...

Abstract

The present invention relates to methods and devices for securing and optimizing data exchange in mobile M2M communication. A method and a device for transferring data from at least one mobile unit, in particular from at least one peer, to a backend system if there is a restricted connection between the mobile unit and the backend system, wherein the mobile unit comprising a local database for storing own data and preferably for buffering data of at least one further mobile unit, wherein the mobile unit generates a local index from stored own data and preferably from buffered data, wherein The backend system includes a master database for storing data received from at least one mobile unit, wherein the backend system generates a master index from the stored data.

Description

technical field [0001] The present invention relates generally to the field of mobile M2M communication, and in particular to utilizing restricted connections for securing and optimizing data transfer. Background technique [0002] The moving process is often monitored and controlled through data analysis and process control in the cloud. [0003] The necessary prerequisite for this is the mobile M2M communication based on the connection between the mobile process element (peer) and the backend (backend) for ensuring data recipients) and for message transmission from backends to peers. [0004] Today's methods only work with online connections with high bandwidth, eg based on public 3G / 4G mobile communication networks. [0005] If the connection to the backend is lost or if the bandwidth is too low, there may be no data transmission to the backend or message transmission to the peer and thus no control and data analysis in the process. [0006] With further automation in ...
